Serial No. 796,172.

To all whom it may concern Be it known that I, OCTAVE fvIILETlE; asubject of the King of Great Britain, residing at No. 479 Fabre street,Montreal, Province of Quebec, Canada, have invented certain new anduseful Improvements in 'Ienoning-Machines; and I do hereby declare thatthe following is a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The invention to be hereinafter described relates to tenoning machines.

In order to more clearly disclose the construction, operation, and useof the invention, reference'should be had to the accompanying drawingsforming part of the present application.

Throughout the several figures of the drawings like reference charactersdesignate the same parts.

In the drawings: Figure 1 is a front view of the machine; Fig. 2 is atop plan view; Fig. 3 is a right end view of Fig. 1; Fig. t is a frontview of the cutting knives; Fig. 5 is a side View of the same, showingthe details of the mountings; Fig. 6 is a fragmentary sectional view ofthe mounting of one of the knives; Fig. 7 is a detail end view of themounting of two of the knives; Fig. 8 is a detail underneath viewshowing the mounting of one of the knives; Fig. 9 is a modified form ofFig. 8; Fig. 10 is a detail showing the adjustment of the knives; andFig. 11 is a side view of the same.

The main objects of the invention are, to provide a machine which willproduce a complete tenon in one operation; which is of simple anddurable construction; which can be produced at a relatively low cost;and which will give a maximum of eiiiciency for the power applied.

Referring to the drawings in detail; a U-shaped frame 1 is secured to asuitable bench or supporting frame, not shown, and provided with lowerintegral shoulders 3 on which a longitudinal beam 4: is mounted. Theupper ends of the sides of frame 1 are provided with angle irons 5which. support an upper horizontal beam 7 above and slightly in back ofbeam at.

A rectangular frame 8 formed of an inner yoke 9 and an outer yoke 10,overlapping the ends of the inner yoke and secured thereto by anysuitable means, is slidably mounted on beam 4 and provided with suitableguide lugs 11. The inner end of the side of yoke 9 is provided with anintegral holding block 12 channeled vertically as at 13. A detachablebracket-iron 14 is secured on the back of block 12, and has its upperend bent so as to extend beneath and in back of the beam 7 and its lowerend bent so as to extend in back of beam 4; thus serving to secure theblock 12 and the elements secured thereto securely mounted on the beam4, as shown in Fig. 3.

For securing the materials to be worked in frame 8, an I beam 15 isslidably mounted in the frame and operated by an adjusting screw 16. Theboard is placed in the channel 13 of block 12 between the blocks 17carried on the inner end of the I beam and the end of the frame 8. Aftersecuring the board in frame 8, the frame is slid along beam 4 by hand orany suitable mechanical means, so as to bring the lower end of the boardinto contact with the cutters 18, which are mounted on a shaft 19rotated by an electric motor, or other suitable means, at high speed.These cutters are mounted on pairs of parallel vanes 20 secured betweensuitable grooved collars 20 and a hub 20 mounted on shaft 19; as in Fig.5; or the vanes may be integral as in Fig. 9, and secured between thecollars 2O only, as in Fig. 7 as preferred. The cutters are set at aslight tangent to the shaft 19 and at a considerable inward angle, andhave their cutting edges slanting downwardly and outwardly, as shown. Asthe cutters engage the board they slice it away, on each side, leavingthe center portion so as to form a tenon. By adjusting the distancesapart of the cutters, the depth of the tenon can be regulated. Toregulate the height of the tenon, the cutters 18 are centrally slottedand secured in position by bolts 21 passed through the slots, andthreaded through the vanes 20, the said bolts being provided withwashers 22 which bear against the upper face of the cutter. By looseningbolts 21 the cutter may be adjusted in relation to shaft 19, so as toregulate the height of the tenon, and then secured in place bytightening the bolts.

In order to get all tenons for the same job of the same height, aslotted plate 23 is mounted so as to be vertically adjustable on frame1, and has its upper end bent upwardly at right angles, so as to form astop or shoulder 24. hen facing the bore in groove 13 of block 12, frame8 is slid back so that the lower end. of the board rests on shoulder 2d,screw 16 is then turned in so as to secure the board between block 17and the end of frame 8, and the front screw 25 is also tightened on theboard, so as to secure it front and back. The board is then fed alongbeam 4 so as to be engaged by the knives, as above described.

It is thought that the construction, operation, and use of the inventionwill be clear from the preceding detailed description.

Changes may be made in the construction, arrangement, and disposition ofthe several parts of the invention, without in any way departing fromthe field and scope of the same, and it is meant to include all suchwithin this application wherein only a preferred form has beendisclosed.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

In a machine of the character described, a U shaped frame, rotary knivesmounted therein, a beam mounted on the frame, a holding frame slidablymounted thereon, means for securing material in the holding frame,adjustable means for adjusting the material carried by the holding framein vertical relation thereto, a second beam secured to the upper ends ofthe sides of the U shaped frame above and in back of the first mentionedbeam, means for slidably securing the holding frame between the twobeams so as to be slidably operative on the first mentioned beam, andmeans for adjusting the rotary knives so as to regulate the depth andheight of the tenon.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
